The Devil’s Horns is one of the most widely recognized symbol of allegiance to Satan. The two raised fingers represent Satan’s horns. Unfortunately, it is also the most incorrectly identified Illuminati hand sign.

The sign made with an extended thumb is used in American Sign Language as a sign for “I Love You”. The sign for the letters I, L, and Y combine to form the gesture. According to researcher Texe Marrs, this is no coincidence, as the creator of the hand sign, Helen Keller, was herself a practicing occultist. (Codex Magica p.120)

Anton LaVey of the Church of Satan also used the the Sign of the Horns.

The Devil’s Horns should not be confused with the Shaka sign, or “hang loose” sign. Emerging from Hawaiian surf culture the sign is made with the hand making a fist while the thumb and pinkie stick out.
